Dependabot has no API to trigger an update check for a single dependency

Engineers maintaining multi-dependency repos often need to check one specific dependency for updates without waiting for Dependabot's weekly schedule or re-running the entire dependency graph. No official GitHub CLI command or API endpoint exposes single-dependency scoped triggering. Renovate gets closest via a Dependency Dashboard Issue checkbox, but that is browser UI only and not scriptable. This CLI tool wraps the dependabot-core update-job API and the GitHub REST API to fire a scoped update job for exactly one package name, optionally across one or all ecosystems, and stream the resulting PR URL or a no-update signal back to the terminal. It ships as a gh CLI extension and a standalone binary so it can be dropped into CI pipelines without browser interaction.
